44: .Sh DESCRIPTION
45: The
46: .Fn utime
1.3 ! jtc 47: function sets the access and modification times of the named file.
! 48: .Pp
! 49: If
! 50: .Fa timep
! 51: is
! 52: .Dv NULL ,
! 53: the access and modification times are set to the current time.
! 54: The calling process must be the owner of the file or have permission to
! 55: write the file.
! 56: .Pp
! 57: If
! 58: .Fa timep
! 59: is
! 60: .Pf non- Dv NULL ,
! 61: .Fa time
! 62: is assumed to be a pointer to a utimbuf structure, as defined in
! 63: .Aq Pa utime.h :
! 64: .Bd -literal -offset indent
! 65: struct utimbuf {
! 66: time_t actime; /* Access time */
! 67: time_t modtime; /* Modification time */
! 68: } ;
! 69: .Ed
! 70: .Pp
! 71: The access time is set to the value of the actime member, and the modification
! 72: time is set to the value of the modtime member. The times are measured in
! 73: seconds since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated
! 74: Universal Time.
! 75: The calling process must be the owner of the file or be the super-user.
1.1 cgd 76: .Pp
1.3 ! jtc 77: In either case, the inode-change-time of the file is set to the current
! 78: time.
